Hi all! We're getting white screen in our DSpace installation. This DSpace
installation has been working since December 2019. Just this week, we're
getting white screen. What I can remember last time I was configuring it
was I was trying to access the Postgresql database through pgadmin 4, so I
returned the previous settings for pg_hba.conf and postgresql.conf. Not
quite sure if this was related to why we're getting the white screen error.
Below is the snippet of the dspace.log:
